One word for leadership is buy-in. As a leader, you have to remember that people have to buy into you and then buy into your vision. People follow leaders they believe in who promote causes that they can believe in. So first develop a working relationship with those who you are trying to lead and then request buy-in. Every message that people hear is, in some way, affected by the messenger that delivers it. Suppose you don't like a particular politician. In that case, everything they say will be colored somehow, and you will not readily receive it if someone else had said. It works that same way, and other aspects of life and leadership people go along with the people they get along with.
As a leader, just because you have a great vision and an idea, however worthy it is as a cause, is not enough to get people to follow you or by into you. You simply have to become an effective leader; you have to get people to buy into you first, and then you get them to buy into your vision. You must work hard to build credibility with people; you must work hard to forge relationships with others. You must work hard to maintain an open line of communication between those you serve in those above you. First, show people that you can achieve results that you can achieve growth in an organization; afterward, they will give you confidence or display in your leadership ability. No one will give you credit for saying, "I told you so," as an organization falls apart. Instead, your success is measured by your ability to take people and lead them in the right direction-changing course.
If you have a vision for leadership in your organization, ask yourself why you lead in the first place? What are you trying to accomplish? Write down a vision statement and see objectively if that vision is worthy of time and effort. See if you can even get a thought down to one word for leadership! If you had to rate the level of buy-in for each and every person you need to buy into a project rater rated on a scale from 1 to 10 and if it's a large organization; try to do by departments or other add-ons and elements to get an assessment but be honest.
Think about ways you can earn credibility with people; specifically, individuals need to develop a good relationship with people by being honest and authentic to develop trust. Hold yourself to high standards and set a good example. They always strive to give people the tools they need to do their jobs more efficiently. It goes a long way by helping others and helping the organization. Help others achieve personal goals and alignment with the organization as a whole and always strive to develop other people you see as potential leaders. Everyone will need a strategy, everyone will need to be specially catered to somehow, but that's okay because leadership takes time and patience. So condensing everything in my body of language into one word for leadership would be this for me; humility.
